These would be ready-made, so there will be not too many choices for handle material. Cocobolo has been my go to wood for a long time. I have some fiddle back maple, some lignum vitae. I would consider other woods but would have to factor the cost into the price.
My go to steel has been 52100. I am very comfortable working with it. There are a couple of other steels that I will use, A2 and PM Stainless, though these won't be available for 2-3 weeks.
I will start with pricing these at $2/mm (and see how it goes), with three choices of wood I listed above. If I use wood like ironwood, price will be updated upward to account for the price difference between my in-house woods and the block.
Western handle with one or two accents adds a considerable time to the total production time. I would like to get more efficient with making western handles, so I am willing to eat some of the cost of producing these. I can make 3 D in place of two western handles.
